Help me overclock my 4790k

Hi guys,

I recently just finished my build:

Asus Maximus VII Hero
i7 4970K
H105 CPU Cooler
Kingston HyperX 16GB (2x8GB) PC3-19200C11 2400MHz Dual Channel Kit

Things I have done so far after the build was finished and hooked up:

- Go into the bios and loaded optimised defaults
- Install Windows 8.1
- Installed vital drivers e.g. LAN card, chipset drivers, video card drivers
- Installed CPU-Z
- Installed OCCT 4.4.0
- Run OCCT on stock settings to check temps.

My current STOCK temps seem to be around 26C idle and 60C load.

I ran OCCT at stock settings just to make sure that the system was stable and after 10 mins I rebooted back into the BIOS.

In the UEFI bios I went to manual overclocking mode and set the multiplier to 42 and changed the vcore to 1.2. I then set the DRAM frequency to 1600 as I want to test the CPU without overclocking the RAM at the same time.

Back into Windows and running OCCT 4.0 and monitoring temps. 10 mins and its doing fine. Will go for 4.4ghz next at 1.2v. If it crashes I will up the volts.

My questions are:

Is this a logical way to overclock. Once I find my limit at the lowest volts I will then start to up my memory frequency.

Are there any other benchmarks you guys recommend?

What are the max volts and temps you guys would recommend for the 4790k with a H105 cooler.

Thanks in advance.
 
lol just realised i should go above 4200, i already tested at 4400!

Doh, great start :)

edit: testing now at 4.6ghz at 1.2vcore. This thread will most likely turn into my personal overclocking diary!

Spent a few more hours tweaking and overclocking. I seem to be stable at 4.7 with 1.24volts. I have upped my Memory to the XMP value (it runs at 2400).

However it caused a BSOD. Does anyone know what setting will make the mem more stable. DRAM voltage is set to 1.65v which is what the manufacturer recommends. Is there a setting to increase the volts for the Memory controller on the CPU?

Thanks

edit: Otherwise I might just drop down to 2133mhz for the memory. I doubt 2400 will make any difference in speed for the applications and games I am going to use.
 
sounds good so far. if it does 5ghz on under 1.3v that would be great.

It isn't going to do 5ghz on less than 1.3v, simple as that.

It might do 5ghz (might being the operative word), but it will take a damm sight more than 1.3v. Unless it is an absolute golden chip - and I am talking the top 1-2%

If you are looking to get highest possible core - keep RAM at 1600mhz until you have a stable oc on the cpu, then try clocking RAM higher than 1600mhz.
 
Yea I had the Ram set to 1600 when i was going for 4.8 stable. I decided however that the temps were getting a bit too high when stress testing so I went back to my stable 4.7 and then started raising the memory frequency. Settled at 2133 for tonight. Will play with it more at the weekend.

Addictive this overclocking lark!
